Hi Peter

Are you sure about that I cannot regulate the 12v?
the transformer output on the pcb look like not connected to any device
neither resistor or capacitor for current feedback.
or maybe the feedback is on the primary coil?
if I draw it's circuit, should it help you see if I can use it? it's very
simple circuit some capacitors and resistors and 2 transistors.

Thanks

Tal

You can't use that transformer as you want, it only works with a normal
bulb (halogen or not), or other resistive load. This is because it uses
current feedback and a saturable core transformer.

The output is insulated at least in theory, because halogen fixtures are
not rated for mains voltage. Check for compliance marks (EC/GS/TUV etc).
However you get to use this only at your own risk ;-).
